A light-emitting device comprises a light-emitting member, which comprises two
electrodes and an organic electroluminescent material disposed between the electrodes,
and at least one organic photoluminescent ("PL") material. The light-emitting member
emits light having a first spectrum in response to a voltage applied across the
two electrodes. The organic PL material absorbs a portion of the light emitted
by the light-emitting member and emits light having second spectrum different than
the first spectrum. The light-emitting device can include an inorganic PL material
that absorbs another portion of the light emitted from the light-emitting member
and emits light having a third spectrum different than both the first and the second spectra.
